There are many indicators and strategies, but most of the time the classical indicators are sufficient (the one which come with our Technical Analysis software). In fact, most indicators are useless, and most strategies are failling (more or less). So... don’t bother with an indicator and start learning basis. Then you’ll choose a trading style / a market as it’s impossible to be good everywhere. And with time and practice you’ll become a winning trader. However, it’s a long process, which usually takes years.
